Important safety instructions
Your BenQ projector is designed and tested to meet the latest standards for safety of
information technology equipment. However, to ensure safe use of this product, it is
important that you follow the instructions mentioned in this manual and marked on the
product.
Safety Instructions
1. Please read this manual before you
operate your projector. Save it for
future reference.
2. Do not look straight at the projector
lens during operation. The intense
light beam may damage your eyes.
3. Refer servicing to qualified service
personnel.
4. Always open the lens shutter or
remove the lens cap when the
projector lamp is on.
5. In some countries, the line voltage is
NOT stable. This projector is designed
to operate safely within a mains
voltage between 100 to 240 volts AC,
but could fail if power cuts or surges
of ±10 volts occur. In areas where the
mains voltage may fluctuate or cut
out, it is recommended that you
connect your projector through a
power stabilizer, surge protector or
uninterruptible power supply (UPS).
6. Do not block the projection lens with
any objects when the projector is
under operation as this could cause
the objects to become heated and

Remote control effective range
Infra-Red (IR) remote control sensors are located on the front and the back of the projector.
The remote control must be held at an angle within 30 degrees perpendicular to the
projector's IR remote control sensors to function correctly. The distance between the remote
control and the sensors should not exceed 6 meters (~ 20 feet).
Make sure that there are no obstacles between the remote control and the IR sensors on the
projector that might obstruct the infra-red beam.
Remote control batteries
1. To open the battery cover, turn the remote control over to view its back, push on the
finger grip on the cover and slide it up in the direction of the arrow as illustrated. The
cover will slide off.
2. Remove any existing batteries (if necessary) and install two AAA batteries observing
the battery polarities as indicated in the base of the battery compartment. Positive (+)
goes to positive and negative (-) goes to negative.
3. Refit the cover by aligning it with the base and sliding it back down into position. Stop
when it clicks into place.
• Avoid leaving the remote control and batteries in an excessive heat or humid environment
like the kitchen, bathroom, sauna, sunroom or in a closed car.
• Replace only with the same or equivalent type recommended by the battery manufacturer.
• Dispose of the used batteries according to the manufacturer's instructions and local
environment regulations for your region.
• Never throw the batteries into a fire. There may be danger of an explosion.
• If the batteries are dead or if you will not be using the remote control for an extended
period of time, remove the batteries to avoid damage to the remote control from possible
battery leakage.

Positioning your projector
Choosing a location
Your projector is designed to be installed in one of four possible installation locations:
1. Table in front of screen;
2. Ceiling in front of screen;
3. Table at rear of screen;
4. Ceiling at rear of screen.
Your room layout or personal preference will dictate which installation location you select.
Take into consideration the size and position of your screen, the location of a suitable power
outlet, as well as the location and distance between the projector and the rest of your
equipment.
1. Front Table
Select this location with the projector placed near the
floor in front of the screen. This is the most common
way to position the projector for quick setup and
portability.
2. Front Ceiling
Select this location with the projector suspended
upside-down from the ceiling in front of the screen.
Purchase the BenQ Projector Ceiling Mounting Kit
from your dealer to mount your projector on the
ceiling.

Note that a special rear projection screen and the
BenQ Projector Ceiling Mounting Kit are required for
this installation location.
Set Rear Ceiling in the System Setup: Basic >

Positioning your projector18
If you use the projector with wireless function, there's no need to worry about data cable
connections.This gives you the flexibility to site the projector anywhere in the room up to a
range of 20m away from your notebook, and switch between presentations on different
notebooks instantly without fiddling with cables
To use the wireless function, you need to install a BenQ wireless module to the projector and
enable your notebook/desktop PC with wireless connection. For more information, refer to
"Wireless connection (optional)" on page 22.
Safety instructions for ceiling mounting of the
projector
We want you to have a pleasant experience using your BenQ projector, so we need to bring
this safety matter to your attention to prevent damage to person and property.
If you intend to mount your projector on the ceiling, we strongly recommend that you use a
proper fitting BenQ projector ceiling mount kit and that you ensure it is securely and safely
installed.
If you use a non-BenQ brand projector ceiling mount kit, there is a safety risk that the
projector may fall from the ceiling due to an improper attachment through the use of the
wrong gauge or length screws.
You can purchase a BenQ projector ceiling mount kit from the place you purchased your
BenQ projector. BenQ recommends that you also purchase a separate Kensington lock
compatible security cable and attach it securely to both the Kensington lock slot on the
projector and the base of the ceiling mount bracket. This will perform the secondary role of
restraining the projector should its attachment to the mounting bracket become loose.
Positioning your projector 19
Obtaining a preferred projected image size
The distance from the projector lens to the screen, the zoom setting, and the video format
each factors in the projected image size.
The maximum (native) resolution of the projector is 1024 x 768 pixels, which is a 4 to 3
aspect ratio (expressed as 4:3). To be able to project a complete 16:9 (widescreen) aspect
ratio image, the projector can resize and scale a widescreen image to the projector's native
aspect width. This will result in a proportionally smaller height equivalent to 75% of the
projector's native aspect height.
Thus, a 16:9 aspect image will not utilize 25% of the height of a 4:3 aspect image displayed
by this projector. This will be seen as darkened (unlit) bars along the top and bottom
(vertical 12.5% height respectively) of the 4:3 projection display area whenever displaying a
scaled 16:9 aspect image in the vertical center of the 4:3 projection display area.
When determining the position of your projector, you should consider its intended use and
input signal aspect ratios. All inputs (other than composite Video being fed a 16:9 aspect
signal) will display in a 4:3 aspect ratio (and will require an additional 33% display height
than that of the scaled 16:9 aspect image projection area).
IMPORTANT: Do not select a permanent projector position based upon a 16:9 projection if you
will ever need to select an input (other than composite Video being fed a 16:9 aspect signal).
The projector should always be placed horizontally level (like flat on a table), and positioned
directly perpendicular (90° right-angle square) to the horizontal center of the screen. This
prevents image distortion caused by angled projections (or projecting onto angled surfaces).
The modern digital projector does not project directly forward (like older style reel-to-reel
film projectors did). Instead, digital projectors are designed to project at a slightly upward
angle above the horizontal plane of the projector. This is so that they can be readily placed
on a table and will project forward and upwards onto a screen positioned so that the bottom
edge of the screen is above the level of the table (and everyone in the room can see the
screen).
If the projector is mounted on a ceiling, it must be mounted upside-down so that it projects
at a slightly downward angle.
You can see from the diagram on page 21, that this type of projection causes the bottom edge
of the projected image to be vertically offset from the horizontal plane of the projector.
When ceiling mounted, this refers to the top edge of the projected image.
If the projector is positioned further away from the screen, the projected image size
increases, and the vertical offset also increases proportionately.
When determining the position of the screen and projector, you will need to account for
both the projected image size and the vertical offset dimension, which are directly
proportional to the projection distance.
BenQ has provided a table of 4:3-aspect-ratio screen sizes to assist you in determining the
ideal location for your projector. There are two dimensions to consider, the perpendicular
horizontal distance from the center of the screen (projection distance), and the vertical
offset height of the projector from the horizontal edge of the screen (offset).

Positioning your projector20
How to determine the position of the projector for a given
screen size
1. Select your screen size.
2. Refer to the table and find the closest match to your screen size in the left columns
labelled '4:3 Screen Diagonal'. Using this value, look across this row to the right to find
the corresponding average distance from screen value in the column labelled 'Average'.
This is the projection distance.
3. On that same row, look across to the right column and make note of the vertical Offset
value. This will determine the final vertical offset placement of the projector in
relation to the edge of the screen.
4. The recommended position for the projector is aligned perpendicular to the
horizontal center of the screen, at the distance from the screen determined in step 2
above, and offset by the value determined in step 3 above.
For example, if you are using a 120 inch screen, the average projection distance is 4432 mm
and with a vertical offset of 302 mm.
If you place the projector in a different position (to that recommended), you will have to tilt
it down or up to center the image on the screen. In these situations, some image distortion
will occur. Use the Keystone function to correct the distortion. See "Correcting keystone" on
page 35 for details.
How to determine the recommended screen size for a
given distance
This method can be used for situations where you have purchased this projector and would
like to know what screen size will fit in your room.
The maximum screen size is limited by the physical space available in your room.
1. Measure the distance between the projector and where you want to position the
screen. This is the projection distance.
2. Refer to the table and find the closest match to your measurement in the average
distance from screen column labelled 'Average'. Check that your measured distance is
between the min and max distances listed on either side of the average distance value.
3. Using this value, look across that row to the left to find the corresponding screen
diagonal listed in that row. That is the projected image size of the projector at that
projection distance.
4. On that same row, look across to the right column and make note of the vertical Offset
value. This will determine the final placement of the screen in relation to the
horizontal plane of the projector.
For example, if your measured projection distance was 4.8m (4800mm), the closest match in
the Average column is 5089 mm. Looking across this row shows that a 3500 mm (3.5 m)
screen is required. If you can only obtain imperial sized screens, the listed screen sizes on
either side of the 3.5 m screen are the 10' and 12' screens.
Checking the min and max projection distance values for these screen sizes, indicates that
the 4.8 m measured projection distance will need to be reduced to fit the 10' size screen, or
increased to fit the 12' size screen. The projector can be adjusted (using the zoom control) to
display on these different screen sizes at those projection distances. Be aware that these
different screens have different vertical offset values.
